WinError.h capitalization in boost/detail/win/basic_types.hpp

Description

If #include <WinError.h> were lowercased to #include <winerror.h>, it would be possible to cross-compile from Linux to Windows using MinGW (and Windows would still be fine because Windows is case-insensitive). A similar change was made to asio in #4491 .

In boost/detail/win/basic_types.hpp .
This affects at least programs that use Boost.Chrono.
